This invention relates to apparatus for loading, transporting, and unloading heavy objects, particularly-logs and the like, and has for its object to provide novel and improved apparatus of this kind whereby logs or the like may be easily and. quickly lifted and their ends placed on a suitable support on which they rest by their own weight while being hauled or skidded, and whereby said logs or the like may be easily and quickly unloaded.

With these objects in view, the invention, generally stated, consists in a wheel-sup? ported swinging arm or standard equipped with suitable means such as a running cable for elevating logs or the like, and a wheelsupported swinging load support, said arm or standard and said load support being suitably connected-for simultaneous swinging movement about their pivots. After the logs or the like have been elevated, the arm or standard is swung about its pivot and the load support is swung simultaneously to load supporting position under the elevated logs 5 while the latter are lowered onto said support.

Preferably all of these operations-are acconiplished by hauling in the cable, as. by

means of a suitable drum.

The int ention is capable of a variety of mechanical expressions, one of which, for

purposes of illustration, is shown in the accompanying drawings, but it is to be expressly understood that said drawings are for purposes of illustration only and are not to be construed as defining the limits of the invention, reference being had to the appended claims for this purpose.

In said drawings- Fig. 1 is a plan view of an apparatus embodying the invention;

Fig. 2 is a side elevation of Fig. 1; Fig. 3 is an end view of the apparatus; Figs. 4and 5 show a cable fairlead viewed from opposite sides; and Figs. 6, 7 .and 8 show successive positions of the apparatus in loading logs or the like, parts being removed for the sake of clearness. 1 w 1 Apparatus embodying the invention may be mounted for'transportation in any suitstandard with the ton able manner, either on a suitable vehicle provided with a source of motive power, oron a wheeled framewhich may be pulled by a tractor or. any other motive power. In the drawings, wherein like reference characters indicate like parts throughout the several views, said apparatus is, by way of example, shown mounted on a supporting body or frame which may comprise ground wheels 1 preferably of the track laying type and provided with a flexible track 2, said wheels being mounted on stub axles 3 carried by frame members 4. ,The frame members 4 are connected by an. axle 5 on which is mounteda, tongue frame 6 which is suitably attached as by means of a pin 7 with any suitable tractor shown diagrammatically at 8. It is to be understood, however, that the specific form of the structure thus far described is not part of the present invention, and that-any suitable structure may be employed.

Pivoted on the axle 5 is an elevating arm or standard of any suitable construction which as shown comprises two curved arms 9 preferably joined by acover plate 10. The elevating arm or standard may be swung from the position shown in Fig. 2 where it rests on suitable stops (.not shown) onthe tongue frame 6 to the position shown in Fig. 6, further movement being prevented by suitable means such as a chain 11 connecting the e frame 6. The standard 9, 10 is equipped with suitable means for elevating logs or the like 12, i

said means preferably comprising a cable 13 passing'over a running sup ort or fairlead on the standard and prefera 1y hauled in to lift the logs 12'by means of a suitable drum 14 which as shown is power operated and .mounted on the tractor 8. As shown particularly in Figs. 4 and 5, the cable fairlead may comprise a. pair of parallel rollers 15 mounted in suitable brackets 16 on the plate 10, and av pair of parallel rollers 17 mounted in suitable. brackets 18 on the plate 10, the axes of rollers 1'6 and 17 being at right angles' The cable 13 passes through the space defined b the surfaces of the four rollers and throug an opening in the plate 10. A swinging load support 19 is pivotedon on f . hinge pins 20, the load support 19 being constituted by a U-shaped frame the legs of which are pivoted on the pins 20. The load support is preferably connected with the standard by means of a, air of links 21, so that as the standard swings about the axle 5, the load support 19 swings simultaneously about hinge pins .20.

"Preferably a swinging bunk 22, which as shown is U-shaped in cross-section, is pivoted on load support 19 by suitable means such as a pin 23 about an axis that is substantially vertical when the load support is in the position shown in Fig. 2. As shown in this figure the ends of the logs rest on the bunk.22 which can pivot about pin 23 when the logs are transported around a curve. When the 10 s are being loaded, as shown in Fi s. 6 and the swinging bunk is preferab y held in its normal transverse position bly suitable means such as a pair of cross 0 ains 24 connecting the standard 10 with the swinging bunk, these chains being slack when the support 19 is in load supporting position as shown in Fig. 2.

The operations of loading, transporting and unloading logs or the like from the apparatus above described are as follows. A suitable number of logs 12 as shown in Fi 6 are connected in the usual or any suitab e manner to the cable 13, which is hauled out manually through the fairlead, the standard and load support being in the position shown in Fig. 6. The cable is then hauled in by means of drum 14 and the logs are lifted until they comeup against the standard as shown in Fig. 7. Continued strain on cable 13 will swing the standard about axle 5 as shown in Fig. 8, the load support 19 simultaneously swinging up toward load supporting position under the elevated logs. As the standard and load support continue to swing to the position shown in Fig. 2,-the logs 12 are lowered to rest on the swinging bunk 22.

In'this position the standard'and load support can be held against further swinging movement by any suitable stops, and the strain on cable 13 can be held by a suitablebrake or the like so as to maintain the parts inloaded position while the tractor 8 pulls the loading apparatus and the logs. In go ing around a curve the bunk 22 will pivot about pin 23 so that the logs 12 may swing,

relative to the loading apparatus without sliding on the bunk. In unloading, the cable 13 is slacked oil and the tractor 8'is set in motion to pull the loading apparatus ahead,

the friction of the logs 12 on the ground rotating the standard and .load support back to the position shown in Figs. 6 and 7 and dumping the logs.

It will be apparent that apparatus embodying the invention is simple, inexpensive,

and strong. Logs to be transported are lifted means for lifting the logs 12 and placing them on the loading support may be employed in place of the cable 13, the winding drum for the cable may be either manually or power operated, the loading apparatus together with the source of motive power may constitute a single vehicle or the loading 1 ap aratus may be constructed as a tractor attac inlent, etc. Changes may also be made in the details of construction and arrangement of the various parts without departing from the spirit of the invention, and reference is therefore to be had to the appended claims for a definition'of the limits of the invention.
